1 ) 7 ( ASSIGNMENT NO APPLICATIONS - FREE PROJECTILE MOTION 1. A projectile is fired from point O and passes through the points A(4,1) and B(6,0). Determine the firing velocity 0 v , the firing angle α , the time required to reach A and B, and velocities at A and B. 2. The highest altitude of a projectile is (17 mt) and its range is (17 mt ) . Determine the firing velocity 0 v , the firing angle , the time of flight, and the alternative firing angle to attain the same range. 3. A ball is projected from point A with a velocity s / m 15 0 = υ , which is perpendicular to the incline shown. Determine the range R on the plane and time of flight. 4. A projectile is fired with an initial velocity s / m 80 0 = and firing angle ) 75 . 0 ( tan 1 = . It hits an incline AB, which forms an angle with the horizontal, at point B. Determine the position of point B, the time of flight to B , and the velocity at B. 5. A projectile is fired horizontally from the edge of a cliff. The horizontal distance from the gun to a target at A is D. Determine the firing velocity 0 v , the alternative firing 0 v B(6,0) x A(4,1) y 0 υ O y x 17m 17m y O α 0 v x α 375m 0 v x y O A H D 30 60 o 0 v B A
